  • Publication number: 20210369124
    Abstract: A system for measuring capillary refill time includes a wearable device and a control unit. The wearable device includes a force sensor to obtain a force signal and an optical sensor to obtain an optical signal. The system ensures that an applied force is acceptable in both magnitude and duration, and that a duration over which the applied force is released or removed is acceptable. These factors can establish that a capillary refill time determined or calculated therein is accurate. The system can also determine the capillary refill time based on the force and optical signals obtained by the force and optical sensors, respectively.

  • Patent number: 11163727
    Abstract: A system, a method, and a computer program product for performing deduplication of data using a scalable deduplication grid are disclosed. A listing of a plurality of zone stamps is generated, where each zone stamp represents a zone in the plurality of zones in a data stream. The listing contains a logical arrangement of the plurality of zone stamps obtained from each storage location and being accessible by a plurality of servers. A first zone stamp in the listing is compared to a second zone stamp in the listing. The first and second zones are delta-compressed based on a determination that the first zone stamp is substantially similar to the second zone stamp. A server is selected to perform the comparison and delta-compression.

  • Publication number: 20210335139
    Abstract: An imaging system for a moving vehicle aggregates pre-existing data with sensor data to provide an image of the surrounding environment in real-time. The pre-existing data are combined with data from one or more 3-D sensors, and 2-D information from a camera, to create a scene model that is rendered for display. The system accepts data from a 3-D sensor, transforms the data into a 3-D data structure, fuses the pre-existing scene data with the 3-D data structure and 2-D image data from a 2-D sensor to create a combined scene model, and renders the combined scene model for display. The system may also weight aspects of data from first and second sensors to select at least one aspect from the first sensor and another aspect from the second sensor; wherein fusing the pre-existing scene data with the sensor data uses the selected aspect from the first sensor and the selected aspect from the second sensor.

  • Patent number: 4375928
    Abstract: This invention consists of a flexible type of concrete guard against the erosion of soil by flowing waters and wave action. It consists of rows of comparatively small, identical concrete blocks which form rectangular sections which are placed upon the ground surface which has previously been covered with a filter cloth. The said blocks are held together by a continuous wire cable which is embedded centrally in each block, and which passes through each row of blocks, forming a small loop as it leaves one of said rows to enter its next adjacent row, by means of which one section can be joined with the other, and pinned to the ground.
